Vivato was granted a rare exception in terms of their certification based on the theory that their base stations antennas apply some intelligence in terms of their directionality toward the specific CPE being talked to. I can also tell you that the exception has no logical scientific rational, in that the same thing can be achieved mechanically and even then in no way reduces the levels of emissions into the cell (which was partly behind the intial rules in the first place).
The FCC was trying to spur innovation and stretch the boundaries, but they also know they are on shaky legal grounds here. I know this from direct meeting with top level folks there. One such meeting was jointly attended with Vivato and WCA LEA's legal counsel. The FCC know they could very likely lose a legal battle should a competing vendor decide to confront the issue. None wish to do so as far as I know though, since partly because vendors appreciate the FCC's attempts to be forward thinking and partly because the has issued the NPRM (comments recently closed) that suggests amendments to these rules (like allowing more power in areas where the noise floor is below certain thresholds or more power when sectorization is used). This NPRM is in part a direct result of their own internal discomfort with their own granted exceptions (Navini was also given one). I hope this helps you to understand this seeming dichotmy.
